inflorescences, scattered on both surfaces of the leaves and here 
more abundant on the midrib and nerves, especially on the lower 
surface. In age the upper surface of the leaf becomes glabrous 
or nearly so. In the type specimen the leaf base across the basal 
auricles is 1 cm in width or less; in the second specimen cited, 
which is sterile, the leaf bases are from 3 to 5 cm in width. 
UROPHYLLUM Wallich 
UROPHYLLUM CAUDATUM sp. nov. 
Frutex glaber; foliis firmiter chartaceis, oblongis ad oblongo- 
lanceolatis, 6 ad 8 cm longis, basi acutis, apice tenuiter caudato- 
acuminatis, nervis utrinque plerumque 5, perspicuis, curvatis; 
fructibus axillaribus solitariis vel binis, globosis, 5 mm diametro ; 
pedicellis 7 ad 10 mm longis. 
A glabrous shrub, the branchlets slender. Leaves firmly char- 
taceous, oblong to oblong-lanceolate, 6 to 8 cm long, 2 to 3 cm 
wide, base acute, apex slenderly caudate-acuminate; lateral 
nerves usually 5 on each side of the midrib, prominently curved, 
distinct, anastomosing, the reticulations rather close, evident; 
petioles 1 to 1.5 cm long, stipules narrowly oblong, blunt, about 
5mm long. Fruits axillary, solitary or in pairs, globose, about 
5 mm in diameter, crowned by the obscurely toothed calyx limb; 
pedicels 7 to 10 mm long, usually with a pair of small bracteoles 
at the base.

This species is apparently most closely allied to Urophyllum 
luzoniense, from which it is easily distinguished by its thinner, 
caudate-acuminate, much fewer-nerved leaves. 
UROPHYLLUM AFFINE sp. nov. 
Frutex perspicue ciliato-villosis; foliis chartaceis, oblongis ad 
oblongo-lanceolatis, 13 ad 17 cm longis, tenuiter subcaudato- 
acuminatis, nervis utrinque circiter 12, perspicuis, utrinque plus 
minusve villosis; floribus ¢ solitariis, ¢ fasciculatis, breviter 
pedicellatis, dense villosis, calycis 4-dentatis, corollae lobis 6, 
anguste oblongis, 3 mm longis, extus villosis. 
A polygamous shrub, the branches, branchlets, petioles, stip- 
ules, flowers and the leaves on both surfaces, especially on the 
midrib and nerves, ciliate-villous. Leaves chartaceous, oblong 
to oblong-lanceolate, 13 to 17 cm long, 4 to 6.5 cm wide, usually 
grayish when dry, base acute to rounded, apex slenderly sub- 
caudate-acuminate, the upper surface and often the margins
